Biological Activity

[Description]:

Lansoprazole(AG 1749) is a proton pump inhibitor which prevents the stomach from producing acid.Target: Proton PumpLansoprazole, a substituted benzimidizole proton pump inhibitor, on pharmacokinetics and metabolism of theophylline has been studied in healthy adults given oral lansoprazole 30 mg once daily for 11 days. On Days 4 and 11 of 300 mg aminophylline was simultaneously administered orally and blood samples for theophylline analysis were taken over 24 h [1]. Patients in the lansoprazole group were significantly less likely to have a recurrence of ulcer complications than patients in the placebo group (P=0.008). There was no significant difference in mortality between the two groups [2]. lansoprazole (AG-1749) and omeprazole, were found to have significant activities against this organism. The activity of lansoprazole was comparable to that of bismuth citrate, with MICs ranging from 3.13 to 12.5 micrograms/ml, and fourfold more potent than that of omeprazole [3]. Clinical indications: Duodenal ulcer; Esophagitis; Gastroesophageal reflux; Gastrointestinal disease; Helicobacter pylori infection; Peptic ulcer; Stomach ulcer; Ulcer; Zollinger-Ellison syndromeFDA Approved Date: May 10, 1995Toxicity: Symptoms of overdose include abdominal pain, nausea and diarrhea.
